Hello There, I've been at least. 10 years use this yogurt cultures and am always amazed at how delicious This yogurt tastes, you have to give only about 14 hours, with the skimmed milk powder (also from Pütz) is the yogurt even tighter. Sometimes like this; sometimes like that. I do everything with it: delicious shakes, mango Lassi, garlic cream to grill. Or simply by itself only with or without sugar. Delicious! And thanks to the probiotic living Cultures even extra-healthy. From my love perfect score. In addition, you create with the above 3 x 2 g loosely over 100 liters of yogurt. This then justifies the price. You can also keep the cultures in the freezer, then hold "almost" forever. You just have to advance very small rollers with a rolling pin, into a small bag and down into the ice. Really just a pinch to 1 liter. Wow!
